Photometric variability of the LAMOST sample of magnetic chemically peculiar stars as seen by TESS. (2023)

Keywords : stars chemically peculiar - stars: rotation - techniques: photometric - binaries: eclipsing - stars: oscillations

Abstract:We analysed space photometry from the TESS mission for a sample of 1002 mCP stars discovered in LAMOST archival spectra. Of the 782 mCP stars with available TESS data, rotation periods were measured for 720 of these. The sample includes 25 stars with additional photometric variability, and 4 eclipsing binaries. With our work, we increase the sample size of mCP stars with known rotation periods and identify prime candidates for detailed follow-up studies. This enables two paths towards future investigations: population studies of even larger samples of mCP stars, and detailed characterisation of high-value targets. ...(more)

Astronomy and Astrophysics policies
Rotational periods and peak-to-peak photometric amplitudes, as measured from TESS photometry, are reported for 720 mCP stars out of the 782 stars observed by TESS. Catalog identifiers, sky coordinates, and spectral types are also listed. Remarks accompany stars which were previously reported as variable, have additional non-rotational signals, and/or to note potential issues with the data.
